上一篇.net core和angular2之前端篇—1 使用的是dotnet模板。之所以用它，因为想用他写webapi，但是写道下一篇的时候遇到点问题，所以先写个分支测试一下。这次是用Node作为服务器——webpack-dev-server。感觉这个demo 好简单啊！
一、新建一个项目目录，这里为F:\Visual Studio Code\app1
二、在项目根目录下添加JSON配置文件：package.json、tsconfig.json、typings.json
{
"name": "webapplication",
"version": "0.0.0",
"private": true,
"scripts": {
"postinstall": "typings install",
"build": "webpack",
"start": "webpack-dev-server"
},
"license": "ISC",
"dependencies": {
"@angular/common": "2.1.1",
"@angular/compiler": "2.1.1",
"@angular/core": "2.1.1",
"@angular/forms": "^2.1.1",
"@angular/http": "^2.1.1",
"@angular/platform-browser": "2.1.1",
"@angular/platform-browser-dynamic": "2.1.1",
"reflect-metadata": "^0.1.3",
"rxjs": "5.0.0-beta.12",
"zone.js": "^0.6.23"
},
"devDependencies": {
"angular2-template-loader": "^0.4.0",
"awesome-typescript-loader": "^2.2.4",
"typescript": "^2.0.3",
"typings": "^1.3.2",
"webpack": "^1.13.0",
"webpack-dev-server": "^1.14.1"
}
}
package.json
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
}
}
tsconfig.json
{
"globalDependencies": {
"es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
}
}
typings.json
三、添加webpack配置文件webpack.config.js
var webpack = require("webpack");
module.exports = {
entry: {
"vendor": "./typescript/vendor.ts",
"app": "./typescript/main.ts"
},
output: {
path: __dirname,
filename: "./js/[name].bundle.js"
},
resolve: {
extensions: ['', '.ts', '.js']
},
devtool: 'source-map',
module: {
loaders: [
{
test: /\.ts/,
loaders: ['awesome-typescript-loader', 'angular2-template-loader'],
exclude: /node_modules/
}
]
},
plugins: [
new webpack.optimize.CommonsChunkPlugin({
name: ['app', 'vendor']
})
]
}
webpack.config.js
四、添加主页面index.html
<!DOCTYPE html>
<html>
<head>
<base href="/">
<title>Angular With Webpack</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<my-app>Loading...</my-app>1111111111111111111111
<script type="text/javascript" src="js/vendor.bundle.js"></script>
<script type="text/javascript" src="js/app.bundle.js"></script></body>
</html>
index.html
五、在根目录下新建目录“typescript”（用户存放ts文件），并依次新建app.component.ts、app.module.ts、main.ts和vendor.ts四个个文件
import {Component} from '@angular/core';
@Component({
selector: 'my-app',
template: '<h1>My First Angular App</h1>'
})
export class AppComponent {}
app.component.ts
import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {AppComponent} from './app.component';
@NgModule({
imports: [BrowserModule],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule {}
app.module.ts
import {platformBrowserDynamic} from '@angular/platform-browser-dynamic';
import {AppModule} from './app.module'
platformBrowserDynamic().bootstrapModule(AppModule);
main.ts
// Angular
import '@angular/platform-browser';
import '@angular/platform-browser-dynamic';
import '@angular/core';
import '@angular/common'; // RxJS
import 'reflect-metadata';
import 'rxjs';
import 'zone.js/dist/zone'; // Other vendors for example jQuery, Lodash or Bootstrap
// You can import js, ts, css, sass, ...
vendor.ts
准备工作已经搞定，然后只需在命令行键入两次命令（npm install、npm start）就搞定了，截图如下：
如上图所示，监听端口是8080，在浏览器输入http://localhost:8080/ ，如下图：
这是做的最简单的一个 angular2 Demo例子。
